回弹是材料变形的特性,在矢量弯管中已成为重要的工艺因素。弯曲不同材料、不同直径、不同厚度、不同弯曲半径的管子以及使用的工装不同时,都会影响弯管的回弹。使用矢量数控弯管机自动弯管,弯出的管形不需校正而达到要求,就必须用回弹数据修正管形数据,得出弯管程序,用以控制弯管机进行弯管。一、回弹数据的计算尽管影响回弹的因素很多,但在弯管机调 Springback is a property of material deformation and has become an important process factor in vector pipe bending. Curving different materials, different diameter, different thickness, different bending radius of the tube and the tool used are not the same, will affect the elbow rebound. The use of vector CNC pipe bender to automatically bend, bend out of the tube without correction to meet the requirements, we must use the springback data to correct the pipe data, draw the pipe program to control the pipe bender to bend. First, the calculation of the rebound data Although there are many factors that affect the rebound, but in the pipe bending machine tune
